This invention relates broadly to coffee making apparatus, and more specifically to a coffee pot of the so-called tricolator ty e more or less commonly employed for tile making of drip cofi'ee.

The primary object of the invention is to provide a simplified construction of drip cofiee maker which shall possess certain marked advantages over the usual commercial forms of devices of this general type.

A further object is to provide a device of embodying my invention;

Figure 2 is a top plan view of the cofi'ee container, detached;

Figure 3 is a view of the same, partly in side elevation and partly in vertical section;

Figure 4 is a detail section showing a modified construction;

Figure 5 is a top plan view of the cofiee container of the modified structure;

Figure 7 is an. enlarged detail section on line 77, Fig. 6. 7

Referring to said drawings, 1 designates a beverage pot having a cylindrical neck portion 2 with a terminal bead or roll 3.; Said roll is adapted to seat in underlying supporting relation to an annular shoulder 4 formed on a water reservoir 5 having a perforated bottom. Said shoulder is located at, or defines, the upper end of a reduced lower end 6 which iseformed on said reservoir: and which isreceived more or less closely wi-thi-n-theembrace of said neck portion 2 of the pot.

An s -internal annular bead 7 13 formed in the :neck'2at a spaced distance 'fromthe-roll 5 3 :so as-tobe positioned inspaced relation to the perforated bottom 8 of the water reservoir 5 when the latter 'isseated on said pot.

Said bead forms .aseat'for an outwardly turned terminal roll 9 formed on the upper end ofthe ground cofiee container 10. This container may be of the cylindrical form shown, or 'it may, if preferred, be tapered somewhat toward its bottom 11,-which latter is provided. with suitably arranged perforations 12 through'which is permitted-drainage frolm the interior of the container to the pot. That portion of the cofiee' container'body located-directly beneath the rollz9 and which 7 is encircled by the head 7 possessessuch less diameter than said bead that, in the seated position of said container, it is maintained out of contact with said bead, thus to Iprovide an intermediate space-or channe'hdesignated bythe. reference character 18, through which 1 ebulliating. water overflowing said container may drainto the pot. Also, to provide avenues through which such .ebulliating water may .freely pass intermediate said bead and the thereon seated roll ofthe coffee container, 7 the metalof the underportionof said roll is, recessed, vpreferablybytheprovision thereiln of a seriesofspacedserrations or notches In the modified construction shown in Figs. 3 to 7, inclusive, the neck 2* ,ofithe beverage pot l lhasiits lower portion tapered, forming adownwardly and inwardly. inclined internal annular seat 15 upon which mayrestthe coffee container 10%, the latter'having itswalls simis5 larlyiin'clined with outwardlythrust corrugations 16 formed therein atthe proper 'level for restingupon said seat,.as'is shown in .Fig. 4.

The corrugations provide passages or avenues through which ebulliating water may no drain to the not. Such corrugations may be continuous throughout the circumference of the container 10 but they are herein shown as provided in separate areas occupying water of-ebullition may'unobstruoted-ly drain to the pot.

In said modified form of the coffee container 10, the terminal roll 9 is turned invide avenues for drainage of overflowing water of ebullition, said container having an inwardly turned terminal roll.

In a drip cofl'eemaker, a pot having a neck with a downwardly and inwardly inclined seat formed in its walls, a cofiee container, mounted interiorly of said neck and having outwardly projecting portions formed in its walls resting upon said seat, said container having an inwardly directed annular terminal edge portion.

In testimony whereof, I aifix my signature. CHARLES KAPNER.

wardly instead of outwardly, thus not only;

to avoid obstruction of the flow of ebulliating water to said drainage passages, but also to. afford means whereby said container may conveniently be'gr'asped to effect its removal from the pot, F
